Abstract: A system for managing assets, and facilitating electronic commerce respecting the assets includes a computerized database for storing asset profiles for a plurality of assets. The asset profiles, each include an asset specification and a bid definition. The asset specification includes maintenance history data for the asset and the bid definition outlines the bounds for one of sale, rental or lease of the asset. Users of the system may search the database remotely over the Internet for desired assets, and retrieve detailed information, such as maintenance history, and then bid on the asset for purchase, rental, or lease. Users can also add their own assets to the database for search by others. The system also includes a fantasy fleet feature for conducting “what if” analyses of a simulated fleet containing existing assets and proposed assets.
